The American magazine Popular Mechanics reported that while the U.S. targeted Iran’s nuclear facilities with bunker-buster bombs during an attack, the facilities likely remained intact due to Iran’s advanced concrete technology, according to a report by webangah News Agency.
The analysis attributes this resilience to the composition and design of Iran’s specialized concrete, which has reportedly withstood repeated tests against penetrating munitions in what the magazine describes as a “silent war.”
The report cites an incident in the early 2000s where a U.S. bunker-buster bomb struck an underground Iranian structure but failed to demolish it-instead becoming lodged within the material unexpectedly.
Popular Mechanics emphasized that Iran has as pioneered ultra-resistant concrete formulations, achieving superiority against such weapons. Earlier iterations of concrete were vulnerable to bunker-busters, but breakthroughs in steel-fiber-reinforced composites altered this dynamic.
The findings align with prior U.S. intelligence assessments confirming Iranian nuclear facilities survived aggressive strikes.
